SUMMARY:CHE 598 Seminar: 3D-Printed Biomedical Devices For Multimodal Haptics, Health Monitoring, and Surgical Applications
LOCATION:Spark
DESCRIPTION:SPEAKER: Dr. Kaiyan Qiu, Berry Assistant Professor, School of Mechanical and Materials Engineering, WSU\n\nBIOGRAPHY:\n\nKaiyan Qiu is currently a Berry Family Assistant Professor in School of Mechanical and Materials Engineering at Washington State University. Dr. Qiu received his Ph.D. in Fiber Science from Cornell University and completed his postdoc training in Mechanical Engineering at Dartmouth College, Princeton University, and University of Minnesota. With his expertise in 3D-printing and        functional materials, Dr. Qiu's current research interests focus on design, manufacturing, and applications of different 3D-printed biomedical devices, including (1) bionic systems for haptics and rehabilitations; (2) wearable biosensors for health monitoring; (3)artificial organs for surgical applications and disease study. Dr Qiu’s highly interdisciplinary research work has been published in numerous high-impact journals. More information about his research can be found in https://www.kaiyanqiu.com/.\n\nABSTRACT:\n\nThe interweaving of functional materials with multiscale, multimaterial 3D-printing processes could enable the additive manufacturing of a diverse set of complex, flexible, multifunctional biomedical devices. To this end, the focus of this research talk is to introduce the 3D-printed biomedical devices with unique geometries and extraordinary functionalities that can be utilized for biomedical applications, including bionic systems, wearable biosensors, and artificial organs. Firstly, a novel high-performance multimodal haptic system on prosthetics, consisting of conformal and modular sensing units for pressure, temperature, and texture detections, will be introduced. This system will be used as a sensing module for a bionic skin system for restoration of  multimodal haptics for amputees. Secondly, multiple 3D-printed wearable biosensors with unique microfluidics, micro-needles, and signal amplification for colorimetric or electrochemical sensing will be introduced. The biosensors can be used for in-situ disease management and health monitoring. Thirdly, a 3D-printed dynamic heart model with physical properties of tissue and integrated electronic sensors will be presented and its applications for edge-to-edge repair on defected mitral valve to reduce regurgitation will be discussed.\n\n
